There is very little difference in the pattern of a 5/16 inverted L
and 1/4 inverted L that has the bend to horizontal at the same height,
assuming a bend even roughly half way. The lower the bend the higher
the maximum lobe takeoff, but it's a mild change. 29 degrees vs. 49
degrees is not correct, all other issues held constant.
